Abstract: A rope fastener includes a body having a pair of parallel apertures slidably receiving two adjacent rope segments defining a loop. The fastener further includes an abutment lug disposed in line with the longitudinal axis of the body. The abutment lug has a first portion extending generally vertically from a second end of the top surface of the body and a generally planar second portion which is connected to the first portion and which extends toward a first end of the body. The first portion may include lateral grooves which receive the loop. The abutment lug is engaged by the loop by folding over the rope to form an attachment loop.

Abstract: The invention concerns a halogen generator submersible in water, the anode and cathode being separated by a salt bed, the chlorine generated at the anode being collected and conducted to the surrounding water via a collecting hood so that the chlorine does not mix with the catholyte or salt bed, the hydrogen formed at the cathode being released through an opening in the generator in the form of large bubbles to promote the flow of water in a tube from a point in the water above the generator to an inlet adjacent the anode whereby there is constituted a flow from anode to cathode to prevent caustic soda migration towards the anode.
